2M ST-LC SM OS1/OS2 Duplex Patch Lead

The 2 m ST-LC SM OS1/OS2 Duplex Patch Lead is a high-quality single-mode fibre optic cable designed for reliable full-duplex data transmission in telecommunications, data centres, and structured cabling systems. Featuring ST connectors on one end and LC connectors on the other, this duplex patch lead enables seamless interconnection between patch panels, optical transceivers, and network equipment.

Constructed with 9/125 µm single-mode fibre, it supports long-distance high-speed transmission with minimal signal loss. The duplex design contains two fibre strands within a single cable assembly, allowing simultaneous transmit and receive communication for full-duplex network operation. Precision-polished ceramic ferrules ensure low insertion loss and stable optical performance.

The durable yellow LSZH or PVC jacket provides protection, flexibility, and easy identification of single-mode fibre. With a compact 2 mm per strand diameter, this 2 m patch lead is easy to route and manage, ideal for high-density rack and cabinet installations.
